Hello there, I am a new affiliate and still struggling to get my hands around the App. The price that we set seems to be fixed or where can it be ammended?

the rooms I listed here can accommodate 2 persons per room sharing the same bed as a couple at no additional cost, however in the rate breakfast is only inclusive for 1 person. if the room is to be occupied by 2 persons, the second person will have to pay additional for the breakfast.  Kindly advise where this ammended can be done. As I found myself accommodating for free!
